The Western and Eastern Ghats

  Exploring the Majestic Mountain Ranges of India: The Western Ghats and Eastern Ghats The Monsoon's Guardians: The Western and Eastern Ghats India's climate is heavily influenced by the monsoon, with nearly 80% of the country's rainfall coming from this seasonal weather pattern. The key to understanding this phenomenon lies in the mountain ranges that line the country's coasts - the Western Ghats and the Eastern Ghats. These two distinct yet interconnected systems play a crucial role in shaping India's weather patterns and natural landscapes. The Mighty Western Ghats Stretching along the western coast of India for over 1,600 miles (2,600 kilometers), the Western Ghats are a continuous range of mountains that were formed during the breakup of the ancient supercontinent Gondwana, some 150 million years ago. This geologically complex mountain system is an active margin, meaning that tectonic activity is constantly shaping and reshaping the landscape. The Wes...

General weather system of India

  General weather system of India Weather & Climate      Climate refer to the sum total of weather condition and variation over large area for a longer period of time. Weather refers to the state of the atmosphere over an area at any point of time. The elements of weather and climate are the same, i.e. temperature, atmospheric pressure, wind, humidity and precipitation. On the basis of the generalized monthly atmospheric conditions year is divided into seasons.      India situated in the northern hemisphere; the tropic of cancer passes through the middle part of the country. As a result the southern half of the country has a tropical climate.  During the winter season in the Northern hemisphere, Northern half of the country is warmer than the areas of similar Latitude about 3° to 8 °  Celsius. This is due the fact that the Himalayas check the cold polar air mass entering into India. In other countries like USA the polar air mass inva...

Cloud formation and precipitation processes

 Cloud formation & Precipitation Cloud formation     Condensation of water above the Earth surface creates clouds. In general cloud develop in any air mass that becomes saturated (relative humidity become 100%).      Saturation can occur by way of atmospheric mechanism that causes the temperature of an air to be cooled to its dew point.  The following processes can be responsible for the formation of the clouds.      W hen air is forced to rise because of the physical presence of elevated land. As the parcel of air rises, it cools due to adiabatic expansion at a rate of approximately 10° C / km.       The development of clouds and resulting heavy quantities of precipitation along SW coast of India, during the SW Monsoon, is due to these processes.      A rain shadow is a patch of land that has been forced to become a desert because mountain ranges blocked all plant-growing, rainy weather.
